Video - Khan Academy Videos are the most commonly used - thanks to Rob, Rebecca, and Jessica for sharing these with us. I use them often as supplementary videos for various units as you can see at the bottom of the Equilibrium topic on my IB wiki.
Calendars - google etc (this is Part 4 of the presentation)
Spreadsheets - google docs
RSS Feeds - possible news sources for science, health, history, politics, language, etc. Updates itself and is a great way to expose students to real-world-examples.
